EVERY US company is legally required to comply with a FISA warrant. Stop acting like Apple has a choice, they don't. And also they are legally considered warrants. Did you read your link?
Apple has a choice about whether or not backups are end-to-end encrypted, using keys unknown to Apple.
Apple, at the request of the FBI, chose to preserve this surveillance backdoor by not deploying their end-to-end encryption system for iCloud Backup, thus making everyone's data available to Apple and potentially responsive to FISA orders. Seriously, read the link:
If that backup data (which includes all your iMessages and attachments thereto) were end-to-end encrypted, which was Apple's original plan, then FISA orders, real warrants, and all the rest would be fruitless as Apple could not decrypt the data. They'd be turning over opaque encrypted data in response to FISA orders and real warrants.
